[0013]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
As shown in FIG. 2, the wall-mounted microwave oven according to the present invention is installed above a microwave oven 10 in a kitchen space. Above the wall-mounted microwave oven of the present invention, there is provided an external duct 20 (see FIG. 3) for guiding the exhaust gas and the smell of food and drink generated by using the gas microwave oven 10 to the outside of the kitchen space.
[0014]
As shown in FIGS. 3 and 4, the wall-mounted microwave oven according to the present invention includes a cooking chamber 31 for cooking food and drinks, and various electric appliances for operating the microwave oven. An electrical equipment room 32 in which components are provided is defined.
[0015]
The cooking chamber 31 is configured such that the front surface thereof can be opened and closed by a door 33, and a control panel 34 for controlling the function of the microwave oven is provided on the front surface of the electrical equipment room 32 in line with the door 33.
[0016]
Inside the electric equipment room 32, there are provided electric components such as a magnetron 32a for supplying high frequency to the inside of the cooking chamber 31 and a high voltage transformer 32b for applying a high voltage to the magnetron 32a. Is provided with a blower fan 32c for cooling the cooling fan.
[0017]
On both sides of the lower plate 30L of the main body 30 of such a wall-mounted microwave oven, exhaust gas generated from the gas microwave oven 10 disposed thereunder and contaminated air containing the smell of food and drink can flow into the main body 30. As described above, the intake port 35 is formed, and the upper plate 30U forming the upper surface of the main body 30 is provided with the exhaust port 36 so that the room air flowing into the inside of the main body 30 through the intake port 35 is discharged.
[0018]
Further, inside the main body 30, there is provided an internal duct 37 for guiding the room air flowing through the intake port 35 to the exhaust port 36. The internal duct 37 extends from the lower part of the cooking chamber 31 and the electrical equipment chamber 32 to the upper part via the rear part, so that the room air introduced through the intake port 35 is guided to the exhaust port 36.
[0019]
Accordingly, the contaminated indoor air flows into the main body 30 through the intake port 35, is guided to the external duct 20 through the internal duct 37 and the exhaust port 36, and is discharged outside through the external duct 20.
[0020]
In such a wall-mounted microwave oven, an exhaust fan assembly 40 that generates a wind blow so as to suck in contaminated room air is provided in the outer duct 20. The exhaust fan assembly 40 includes a fan motor 41 that generates a rotational force, an exhaust fan 42 that rotates by receiving the rotational force from the fan motor 41 and generates a wind force, and installation of the fan motor 41 and the exhaust fan 42. And a fan case 43 for The fan motor 41 is inserted in the center of the fan case 43, and one exhaust fan 42 composed of a centrifugal fan is provided on each side of the fan motor 41. At this time, since the exhaust fan assembly 40 is installed in the external duct 20 without being installed in the main body 30, the sizes of the main body 30 and the cooking chamber 31 are not limited. For example, the size of the main body 30 and the cooking chamber 31 need not be increased to accommodate a large exhaust fan assembly having increased airflow and capacity.
[0021]
On both sides of the fan case 43, suction holes 43a for sucking contaminated air are formed, and on the upper surface, discharge holes 43b for discharging the contaminated air flowing into the fan case 43 are provided. Therefore, the exhaust fan assembly 40 draws in contaminated room air on both sides and discharges it on the upper side.
[0022]
In the present embodiment, since the discharge holes 43b are provided on the upper surface of the fan case 43, contaminated room air is discharged upward. However, it can be seen that the discharge hole 43b can be located in another part or on another surface of the fan case 43 according to the shape and position of the external duct.
[0023]
FIGS. 5 and 6 show a microwave oven according to another embodiment of the present invention. In order to arrange the discharge hole 43b on the front or rear surface of the fan case 43, the shape and position of the external duct 20 'or 20 "are changed. Thus, the exhaust fan assembly 40 can be arranged so that the exhaust hole 43b faces forward, or the exhaust fan assembly 40 can be rotated so that the exhaust hole 43b faces rearward. The air can be exhausted forward or backward of the microwave oven, for example, FIGS. 5 and 6 are arranged or guided to guide contaminated room air forward of the microwave oven to turn room air electronically. Shown is an exhaust fan assembly 40 arranged to guide behind the range, in which case a guide plate 100 is provided at the top of the body 30 to remove contaminated air from the external duct 20 '. It can be guided to an exhaust passage (see the arrow from the external duct) provided in the main body 30. This exhaust passage communicates with the cooking space of the kitchen. An air filter (not shown) may be provided for filtering before discharging into the cooking space of the kitchen.
[0024]
Hereinafter, the operation and effect of the wall-mounted microwave oven according to the present invention will be described in detail with reference to FIGS.
When power is applied to the exhaust fan assembly 40, the exhaust fan 42 is operated by the fan motor 41 to generate a blown air, and the blown air causes the contaminated room air to flow through the intake port 35 provided in the main body 30. , Through the internal duct 37 and the exhaust port 36 in order. After that, the air flows into the fan case 43 through the suction holes 43 a provided on both sides of the fan case 43. Next, the contaminated air passes through, for example, a discharge hole 43b (see the embodiment in FIG. 4) provided on the upper surface of the fan case 43, and is then discharged along the external duct 20 to the outside of the cooking space of the kitchen, for example. .
[0025]
Since such an exhaust fan assembly 40 is not installed in the main body 30 but installed in the external duct 20, the capacity of the cooking chamber 31 is reduced to accommodate the large fan motor 41 and the exhaust fan 42. The large capacity fan motor 41 and exhaust fan 42 can be applied to a wall-mounted microwave oven. Rather, the volume of the cooking chamber 31 can be increased as compared with a conventional microwave oven in which an exhaust fan assembly is provided in a main body having the same size as the main body 30 of the present invention.
[0026]
【The invention's effect】
As described above, the wall-mounted microwave oven according to the present invention has a large-capacity exhaust fan and fan regardless of the volume of the main body and the cooking chamber because the exhaust fan assembly is separately installed in the external duct instead of the main body. The motor can be applied and the volume of the cooking chamber can be increased. In fact, the volume of the cooking chamber can be increased by providing the exhaust fan assembly in an external duct.
[0027]
Further, since the exhaust holes can be directed in various directions by rotating the exhaust fan assembly, the indoor air exhaust direction can be easily changed according to the shape and position of the external duct.
